National Electric Power Regulatory Authority (NEPRA) Thursday approved to hike power tariffs by Rs. 1.77 per unit on request by Central Power Purchasing Agency (CPPA). The power tariffs have been raised for the month of September. According to National Electric Power Regulatory Authority (NEPRA), tariffs of power distributing companies have been revved up under monthly fuel adjustment, as electricity to the tune of 8.11 billion units, was sold out to these companies during September. According to NEPRA sources, the electricity prices were raised due to soaring cost of furnace oil. The recent hike is not applicable to Karachi Electric Supply Company (KESC) and lifeline users. It should be pertinent to note here that the CPPA pleaded the NEPRA to hike tariffs by Rs. 1.80 per unit. The NEPRA had already hiked the power tariffs by Rs. 5.08 for the months of July and August.
